I challenge you not to look at this and make a ping/spring/boing happy sort of a noise.

Wow, thanks to Emily's Blog we now know more.

The part "not manufactured to a precise enough specification" is the "rail at the bottom". It tends to binds some doors while allowing others to open fine. While that sounds a bit sketchy to me it fuelers my hope that the other side of TEGA will be fine.

More from her blog:

Finally, Leslie cleared up something I've apparently been confused about for a while. The reason they're pressing toward getting an ice-rich sample for TEGA is because of concern about a possible short. This short is a "high-side" short that could affect the whole instrument. It is not the same as the short that affected oven 4; that one is "cleared," it can't possibly affect the operation of TEGA in the future.

So now we know this is another short. Not good news to hear, but on the positive side according to what Leslie Tamppari told Emily the team looking for a possible sol 60 rasp & deliver. The long wait is finally over, we just have to sit out this weekend.

Thanks Emily for that update!

No. We don't. What Emily reported is what has been discussed previously--the team is worried about a "possible" future short that could threaten all ovens. There is something unknown that caused one short (in TA 4). There are types of shorts that are local to the oven, like that one. As Emily said, there are high side shorts that affect the entire instrument. There is "no way to assess the probability of another short circuit" occurring, so prudence dictates knocking off the highest priority samples first (http://phoenix.lpl.arizona.edu/07_02_pr.php). Once there is another short, it may simply be too late to be prudent.
